Light Cruiser RNN Tromp.

Description

These appear to have been Wilton-Fijenoord versions of the Bofors 15 cm Mark 6. Marks 9 and 11 were for twin mounts while the Mark 10 was for single mountings. All these guns used horizontal sliding breech-blocks and had similar ballistics. Surviving ships were supplied with British-built munitions during World War II.
